Answer 1

Key Points

The degree to which observed values/scores are free from errors of measurement is reliability.

Reliability:

Reliability is the consistency of scores over time, across different items, or with different judges. It measures how well a test measures what it is supposed to measure.
A reliable test will produce similar scores when it is taken by the same person on different occasions or when different items are used to measure the same construct.

Additional Information

Content validity is the extent to which a test measures the content that it is intended to measure. It is assessed by examining the test items to see if they are representative of the content domain that the test is supposed to measure.
Construct validity is the extent to which a test measures a theoretical construct. It is assessed by examining the relationship between the test scores and other variables that are theoretically related to the construct.
Criterion validity is the extent to which a test predicts a future behaviour or outcome. It is assessed by examining the relationship between the test scores and a criterion measure of the behaviour or outcome.

Therefore, the answer to this question is 1) Reliability.
